About compressing to this size
100 KB is a tight limit, usually meant for one page: an ID card, a photo of a certificate or a signed form. One clear phone photo normally fits once it is resized for the page.
How it stays under 100 KB: the tool builds the PDF, checks its size, and if it is too big it lowers the image resolution and JPEG quality step by step, keeping the best-looking version that fits. Pages keep the same layout either way, so the document still looks like the original.
Tips: photograph documents flat, in daylight, and crop the edges before adding them — clean images shrink much better. If several pages can’t reach 100 KB, remove pages you don’t need or split them into two uploads.
Need a different limit? 200 KB · 300 KB · 500 KB · 1 MB — or type any number into “Max PDF size” above. Already have a PDF that is too big? Use Compress PDF to 100 KB.
Frequently asked questions
How do I convert JPG to PDF under 100 KB?
Add your photos above, put them in order and click “Create PDF”. The limit is already 100 KB, so the PDF you download stays under it.
Can I combine several photos into one PDF?
Yes. Add as many as you need; each photo becomes one page, in the order shown. Use the ↑ button to reorder.
What if it can’t get under 100 KB?
You’ll get the smallest possible PDF and a note. Use fewer photos, crop them, or split the document into two files.
Are my photos uploaded?
No. The PDF is made in your browser — your documents never leave your device.
